I wonder what this actually represents in Tokyo, where I live. Trains, restaurants and more are packed as usual, though Citymapper claims it’s one of the least mobile cities now - guess that might be more a representation of the fact that barely anyone here uses Citymapper at all since the data is much worse than local apps, and whoever is might be risk averse? Not to mention, when I used Citymapper I pretty much never hit the Go button, which would mess with their definitions as well.
